Do you have any water in your formula? If not will it be in any contact with water?

I make some similar products, and haven’t been putting any preservatives in it, with no problems. Maybe that’s wrong, but my products should not have any contact with water.

can you make sure that the Hemp Extract is oil base not water base?

No water in the formula or are we planning on adding water.

Yes. The hemp extract is oil based.

I have read that the citrus essential oils would work as a preservative. Is there any truth to this claim?

@Bios - it wouldn’t be effective for most formulations. Depending on the type there are also safety concerns when applied to skin.

@Bios

Linatural CO-NLP-1

Certified organic orange / lemon grass / sunflower oils / natural alcohol

I’ve used this in conjunction with Lexgard Natural in a clay-based product and it passed PCT.

Since you have an anhydrous formula, you should not have any issues.

Agree with Perry … an EO-based preservative would most likely not be effective in most formulas if used solo.

Mark, isn’t d-Limonene the factor in that NLP-1 concoction?

I suspect so … that and the alcohol. I’ve never looked at a compositional analysis of it, but you are probably correct.

Any opinions on Japanese Honeysuckle Extract as a possible preservative?

I’ve use it with both success and failure … so you will be best off coupling it with hurdle technology and possibly a complimentary preservative

@Bios - it works great when it is spiked with parabens and formaldehyde donors. https://personalcaretruth.com/2010/07/honeysuckle-plant-extract/

The “active” in the Honeysuckle is actually a paraben precursor. Though not technically a paraben, the molecular structure is very close to parabens.
